I was treated badly during the check-in process, so I ended up canceling my reservation. Check-in is at 3:00, I showed up at 3:30 and was notified that my room was not ready(I made reservations days in advance). There weren't any other accommodations presented to me. I was told that I had to "wait around" until a room became available. It felt like I was being discriminated against. The night before checking in, I stayed at the Venetian, so I ended up going back to that hotel.
